(0.04)^-1.5 on simplification gives: 

Direction : What value should come in the place of question mark (?) in the following questions?

80% of 10% of 340 = ?

If (a + b):(b + c):(c + a) = 7:6:5 and a + b + c = 27, then what will be the value of 1/a: 1/b :1/c?

Find the value of given expression. 

[76 – {90 ÷ 5 ⨯ (24 – 36 ÷ 3) ÷ 3}] 

Direction : What value should come in the place of question mark (?) in the following questions?

125% of 2440 – 75% of 1856 = ?

What is the value of X ?, if 7580 - X = 3440

The value of   $$ {(0.03)^2 - (0.01)^2}\over 0.03-0.01 $$

Simplify the following equation
$$ {\sqrt{(1-sin^{2}θ) ÷{(1-cos^{2}θ)}}}$$
